ABSTRACT

A cosmetic raw material using a vinyl polymer containing carbosiloxane dendritic structures and fluorinated organic group as the main or most important ingredient, a cosmetic product obtained by compounding with the cosmetic raw material, and a method for manufacturing a cosmetic product, in which said cosmetic raw material is mixed with other cosmetic raw materials. The cosmetic raw material exhibits superior compounding stability in cosmetic products and capable of imparting excellent feel and surface protective properties to cosmetic products. The cosmetic product exhibits superior adhesion to the hair and skin.

The present invention relates to a cosmetic raw material, a cosmeticproduct, and a method for manufacturing a cosmetic product.Specifically, it relates to a cosmetic raw material exhibiting superiorcompounding stability in cosmetic products and capable of impartingexcellent feel on application and surface protective properties tocosmetic products, to a cosmetic product obtained by compounding withthe cosmetic raw material, and to a method for manufacturing thecosmetic product. Cosmetic where used herein includes the application tothe body for purposes other than beautifying, such as administering ofmaterials to skin.

In the past, vinyl co-polymers of radical polymerizable monomers andorganopolysiloxanes containing radical polymerizable groups have beenknown to be used as cosmetic raw materials. For instance, JapanesePatent Application Publication No. Hei 5-000924 offers a base oil for ahair dressing agent consisting of a vinyl polymer obtained bypolymerizing methacrylic acid and tertiary butyl acrylate with adimethylpolysiloxane oligomer containing methacrylic groups. While thisvinyl co-polymer does give water repellent properties and slip tocosmetic products, its compatibility with other cosmetic raw materialsis low, and its compounding stability is inferior. In addition, as aresult of insufficient adhesion to the hair and skin, it easily washesoff and has inferior surface protective properties. A cosmetic rawmaterial using a vinyl polymer with carbosiloxane dendritic structuresin side chains as its main ingredient has been proposed with a view tosolve such problems (see EP 963751). However, the water repellency, oilrepellency, skin-oil resistance, and adhesion to the hair and skin ofsuch a vinyl polymer are still not completely satisfactory.

The inventors arrived at the present invention as a result of in-depthinvestigations aimed at overcoming the above-described problems. Namely,it is an object of the present invention to provide a cosmetic rawmaterial exhibiting superior compounding stability in cosmetic productsand capable of imparting excellent feel on application and surfaceprotective properties to cosmetic products, a cosmetic productexhibiting superior adhesion to the hair and skin obtained bycompounding with said cosmetic raw material, and a method formanufacturing the cosmetic product.

The vinyl polymer solution or suspension used in the cosmetic rawmaterial of the present invention can be easily prepared by mixingsilicone oil, organic oil, alcohol, or water with the vinyl polymer. Inaddition, these liquids may be present during the polymerization of thevinyl polymer. In this case, it may be necessary to completely eliminatetheir odor by removing all residual unreacted vinyl monomers bysubjecting the solution or dispersion to heat treatment under normal orreduced pressure. Moreover, pigments such as iron oxide and particles ofinorganic oxides, such as titanium oxide, silicon oxide, mica, talc,etc., which are allowed to be used as cosmetic ingredients in cosmeticmaterials, can be compounded or combined with the solutions anddispersions. In addition, in case of dispersions, surfactants may beadded in order to improve the dispersibility of the vinyl polymer. Suchsurfactants are exemplified by hexylbenzenesulfonic acid,octylbenzenesulfonic acid, decylbenzenesulfonic acid,dodecylbenzensulfonic acid, cetylbenzenesulfonic acid,myristylbenzenesulfonic acid, and their sodium salts and other anionicsurfactants; octyltrimethylammonium hydroxide, dodecyltrimethylammoniumhydroxide, hexadecyltrimethylammonium hydroxide,octyldimethylbenzylammonium hydroxide, decyldimethylbenzylammoniumhydroxide, dioctadecyldimethylammonium hydroxide, tallowtrimethylammonium hydroxide, coconut oil trimethylammonium hydroxide,and other cationic surfactants; nonionic surfactants based onpolyoxyalkylene alkyl ethers, polyoxyalkylene alkyl phenols,polyoxyalkylene alkyl esters, polyoxyalkylene sorbitan esters,polyesters and ethylene oxide adducts of polyethylene glycol,polypropylene glycol, and diethylene glycol trimethylnonanol; as well asmixtures of two or more of the above surfactants. In such dispersions,the average particle size of the vinyl polymer is preferably in therange of from 0.001 to 100 μm, and, even more preferably, in the rangeof from 0.01 to 50 μm. This is due to the fact that if the averageparticle size falls outside the indicated ranges, the feel produced onapplication by cosmetic products compounded with the polymer, and, inparticular, finger and skin feel, as well as its spreadability, tend tobe insufficient.

The cosmetic raw material of the present invention as described above ischaracterized by exhibiting superior stability in cosmetic products,imparting excellent feel on application and surface protectiveproperties to cosmetic products, and, furthermore, improving their waterrepellency and oil repellency. In particular, when used in skincosmetics, it has the advantage of superior water repellency, gas andmoisture permeability, as well as the advantage of being unlikely tocause an unnatural, sticky skinfeel while imparting a clean and neatsensation, and, when used as a hair cosmetic material, has the advantageof imparting water repellency and hair-setting properties. In addition,because of its superior skin-oil resistance, it is characterized bysignificantly improving adhesion to the skin and hair. Thus, thecosmetic raw material of the present invention is suitable for use as araw material for skin cosmetics and hair cosmetics.
